Sebastia-Forcada E, Lizaur-Utrilla A, Mahiques-Segura G, et al. - This research was sought to ascertain if there were long-term variations in outcomes of reverse shoulder arthroplasty (RSA) undertaken for acute proximal humeral fracture versus rotator cuff deficiency with a minimum follow-up of five years. Researchers performed a prospective cohort study including a total of 67 patients with acute complex proximal humeral fracture and 64 patients with irreparable rotator cuff deficiency who had undergone primary RSA. The results considered that RSA may be applied not only for individuals with irreparable rotator cuff deficiencies, but also for those with acute complex proximal humeral fractures. The findings revealed that RSA gave similar functional outcomes and a low revision rate for both indications at the long-term. Nevertheless, in patients with an acute fracture, satisfaction is lower.
